Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0013] Such as figure 1 A fire hydrant is shown, the fire hydrant has a cylinder 1 with a cavity 2 inside, the upper part of the cylinder 1 is provided with a water outlet 3 for connecting with an external hose, and the lower part of the cylinder 1 is connected with an underground The water supply pipe is connected to the water inlet pipe 4, and the cylinder body 1 is provided with a valve body for limiting whether the water outlet interface 3 is water-out or not. When the fire hydrant needs to discharge water, the valve body 5 is opened, and the water is drawn from the water inlet pipe 4 through the cavity 2 of the cylinder body 1 from the water outlet interface 3 .
[0014] A water outlet 6 is opened on the side wall of the cylinder body 1 , and the water outlet 6 is opened on the side wall of the lower part of the cylinder body 1 . The water outlet 6 is ...

The invention relates to a water drainage device of a fire hydrant. The fire hydrant is provided with a hollow cylinder body; a water outlet interface connected with an external water hose is formed at the upper part of the cylinder body; the lower part of the cylinder body is communicated with an underground water supply pipe; and a valve body used for controlling the connection between the cylinder body and a water inlet interface is arranged at the communicated portion; a water outlet is formed on the side wall of the cylinder body; and the water outlet is formed on the side wall of the lower part of the cylinder body. By using the fire hydrant provided by the invention, the water accumulated in the cylinder body can be effectively drained in time through the water outlet so that unsmooth water outlet, even blockage, caused by rusting or icing, is effectively prevented.
Description
technical field [0001] The invention relates to a drainage device of a fire hydrant. Background technique [0002] Generally, the cylinder of the fire hydrant is usually hollow, the upper part of the cylinder is provided with a water outlet, the lower part of the cylinder is connected to the underground water inlet, and a valve body is set at the connection to control the opening and closing of the cylinder and the water inlet. When extinguishing a fire, water flows through the hollow cylinder and sprays out from the water outlet. But often after use, there will be accumulated water in the hollow cylinder, and it is easy to cause rust inside the cylinder, especially the lower part of the cylinder after a long time; when the weather is cold in winter, the accumulated water in the cylinder is easy to Freezing, when the water needs to be discharged, it is easy to block the inside of the cylinder, resulting in poor water discharge or even no water discharge. Contents of the ...
